造方法とその釣り竿を合理的に得る点にある。Here, considering the work of externally fixing the seat base to the rod material, in the prior art, the inner surface of the cylindrically formed sheet base is fixed by bonding to the outer surface of the rod material. Therefore, it is necessary to apply an adhesive during work. Regarding a rod material, a fishing rod material called a glass rod or a carbon rod is manufactured by sintering a sheet-shaped prepreg wound around a loose tapered core (mandrel). So, its outer surface is also a loose tapered surface,
In the rod material manufactured in this manner, if an error occurs in the cutting positions of both ends after the core metal is removed, the outer diameter value of the rod material at a predetermined position with respect to the end of the rod material is also determined. Due to errors, when trying to fix the seat base as described above, a gap is created between the inner surface of the seat base and the outer surface of the rod material, which may cause rattling, or the seat base may be fed to a predetermined position. There is a need for a technique for reliably forming the seat base at a fixed position on the outer surface of the rod material, which may cause the inability to fit. Therefore,
It is also conceivable to dispose a mold on the outer surface of the rod material and inject a resin between the mold and the rod material, that is, to directly form the leg receiving portion on the outer surface of the rod material by so-called injection means. However, since the rod material is formed by winding a sheet-shaped prepreg around a mandrel, the thickness of the overlapping portion of the prepreg becomes large after molding, and the outer shape of the prepreg is unlikely to be a perfect circle. Therefore, even if the mold is directly arranged on the outer surface of the rod material having such a shape, it is difficult to bring the mold and the rod material into close contact with each other, and the resin leaked from the mold after molding,
There is room for improvement, such as removal of burrs, which is troublesome. SUMMARY OF THE INVENTION An object of the present invention is to provide a method of manufacturing a fishing rod in which a leg receiving portion having a predetermined shape at a predetermined position of a rod material is formed reasonably and firmly, and to obtain the fishing rod rationally.

向上させることも可能になる。When the above features are configured as shown in FIGS. 1 to 3, for example, when the seat bait 4 having the leg receiving portions 1 of the reel is formed on the rod material 6, the outer surface of the rod material 6 is The annular body 7 is externally fitted and fixed, and the dies 8, 8 are arranged on the outer surface of the annular body 7, so that the outer surface of the annular body 7 and the inner surfaces of the dies 8, 8 are in close contact with each other. Mold 8,
A resin injection space is formed between the outer surface of the rod material 6 and the rod material 6, and in this state, the resin P is injected into this space.
The sheet base 4 is formed in a form integrated with the rod material 6 in a state where the resin P injected from between the sheet base 4 and the resin material 8 does not flow out. In other words, in the present invention, by setting the outer diameter of the annular body 7 in advance so as to be in close contact with the inner surface of the mold 8, burrs are less likely to occur during molding, and the leg receiving portion is formed by molding. As described above, not only is the step of manufacturing the sheet base 4 as a separate body unnecessary, but also the step of applying an adhesive is not required. Thus, the leg receiving portion can be integrally formed with the rod material 6 in a state in which the outflow of water is suppressed. In particular, in the fishing rod of the present invention, the center of gravity of the seat base can be made to coincide with the axis of the rod by setting the shape of the annular body and the fixing position of the external fitting, and the balance of the rod can be improved.
